In a study of 23 intra-articular fractures of the distal tibia of which 18 were re-examined after an average follow-up period of 5.4 years, two major fracture patterns were identified: type A, a rotational pattern, caused by low energy trauma and type B, a compressive fracture pattern caused by high energy trauma. Type B fractures could be divided into three subgroups: 1) An isolated fracture o...

The saltwater crocodile is the largest of all living reptiles. It is also known and proved that it has the largest biting forces. The magnitude of the biting force exerted by the jaw leads to thoughts about the anatomical structure and construction of the jaw joint in this reptile. Thirteen skulls of the saltwater crocodile (C. porosus) were used for this study. Some skulls were used for X-rayi...

Dehydroepiandrosterone (DHEA), a precursor of sex steroid hormones, is synthesized by cholesterol side-chain cleavage cytochrome P-450 and 17alpha-hydroxylase cytochrome P-450 mainly from cholesterol and converted to testosterone and estrogen by 3beta-hydroxysteroid dehydrogenase (3beta-HSD), 17beta-HSD, and aromatase cytochrome P-450. Although sex steroid hormones have important effects in the...

Osteoarthritis has as main characteristics the degradation of articular cartilage and the formation of new bone at the joint edges, so-called osteophytes. In this study enhanced expression of TGF-beta1 and -beta3 was detected in developing osteophytes and articular cartilage during murine experimental osteoarthritis. To determine the role of endogenous TGF-beta on osteophyte formation and artic...

OBJECTIVE The purpose of this article is to review the current understanding of the MRI appearance of articular cartilage and its relationship to the microscopic and macroscopic structure of articular cartilage, the optimal pulse sequences to be used in imaging, the appearance of both degenerative and traumatic chondral lesions, the appearance of the most common cartilage repair procedures, and...

Lipoma arborescens arising in the extra-articular bursa of the knee joint is extremely rare. We describe an 11-year-old boy who complained of a gradual swelling mass of the lateral knee joint. Magnetic resonance imaging (MRI) showed a high signal intensity tumor on T1- and T2-weighted images with a thickened septa and nodular lesion that showed low signal intensity. The radiologist suggested th...

Articular cartilage defects are common and play a significant role in degenerative joint disease. Cartilage is unable to regenerate, secondary to an inherent lack of vascular supply, thus, various techniques have been described in an attempt to treat and potentially restore these defects. Treatment decisions should be based on appropriate evaluation and classification of the pathology. Only the...

Excessive femoral anteversion may lead to increasing stress placed on the anterior acetabulum and soft tissues, which can predispose to intra-articular hip pathology. By addressing the excessive femoral anteversion in combination with intra-articular hip pathology, the results will be durable over time. This technique details how to perform a femoral derotation osteotomy for excessive femoral a...

Articular cartilage-on-bone has been subjected to repeated impact loading in vitro and the associated structural changes occurring in the general matrix examined by optical and transmission electron microscopy (TEM). The study shows that repeated trauma transforms the pseudorandom arrangement of fibrils comprising the general matrix of normal articular cartilage into a structural configuration ...

Twenty-six patients with frozen shoulder syndrome (Stage 2 and 3) were included in this study conducted at Dr. Kariadi General Hospital, Semarang, Indonesia and randomly allocated into 2 groups: 40 mg triamcinolone intra-articular injection and triamcinolone oral tablets. The result showed that triamcinolone intra-articular injection group "cured" rate was 5.8 times higher at week one compared ...
